Who is responsible for a retaining wall between neighbours?

Retaining walls are not treated as dividing fences under Queensland law, so the usual fence-cost-sharing rules don’t apply.

Who usually pays?

Responsibility usually rests with the property that benefits from the wall, or the owner of the land where the wall is located. Every situation is different, particularly where the wall straddles a boundary or supports both properties.

Before construction

• Confirm the boundary position
• Talk to your neighbour before you start
• Put agreements in writing
• Check whether approval is needed

Retaining wall disputes can become complex. If ownership or responsibility is unclear, get independent legal advice. This article is general information only.
